RABAT: A strong 6.1-magnitude earthquake struck early Monday in the Mediterranean between Morocco and Spain, the US Geological Survey said. The shallow quake hit at 4:22 am (0422 GMT) 62 kilometers north of the Moroccan city of Al Hoceima and 164 kilometers east-southeast of Gibraltar, the USGS said. It was followed by a 5.3-magnitude tremor. Tremors were felt in the south of Spain and in the Spanish enclave of Melilla bordering Morocco, but the authorities reported no victims. “For the moment there has been only material damage and we haven’t detected any that is very serious,” Isidro Gonzalez, a Melilla official, told Cadena Ser radio. In the Malaga area in southern Spain, on the other side of the Strait of Gibraltar, many inhabitants also felt the earthquake. In February 2004 a strong 6.3 earthquake that hit near Al Hoceima killed nearly 630 people.
